Thanks Pierre, Greg.
I had thought that `nothing' is same as null string.
But manual says that preamble and postscript are optional.
So I thought that like bellow.
{,c} is a same format as a{,c} except preamble.
So these generate two strings.
a{,c} generates 'a', 'IFS' and 'ac',
{,c} generates '', 'IFS' and 'c'.
That is incorrect...
What's different about nothing and null string?
Sorry, my name is garbled.
